In mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. If you have any queries and feedbacks regarding these program source codes for Matrix Multiplication in C, you can mention and discuss them in the comments box below. Would love your thoughts, please comment. C uses “Row Major”, which stores all the elements for a given row contiguously in memory. The matrix multiplication takes place as shown below, and this same procedure is is used for multiplication of matrices using C. Solving the procedure manually would require nine separate calculations to obtain each element of the final matrix X. if i # j aij = 0 ) a) Use the definition of matrix multiplication to show that the product of any two diagonal matrices is a diagonal matrix. There are three separate user-defined functions in this program to read data, preform matrix multiplication operation and display the resultant matrix. by Marco Taboga, PhD. These nine separate calculations have been done using very few lines of code involving loops and function in this C program for Matrix Multiplication.

We should have basic knowledge on the representation of two dimensional matrix in C. Here is three two dimensional matrix a, b and c. a for matrix A, b for matrix B, and c for matrix C. which holds the multiplication result.i, j, k are control variable and sum is needed to hold the summation of the consecutive two products. A diagonal matrix is sometimes called a scaling matrix, since matrix multiplication with it results in changing scale (size). Running them on Turbo C and other platforms might require a few modifications to the code. Our main mission is to help out programmers and coders, students and learners in general, with relevant resources and materials in the field of computer programming.
